There are a few templates that vB calls to to produce such a notice, if you are wanting to change every one then you need to do your edits in each template alike.

Search for 'standard_error' in your style manage > search in templates

You should see
STANDARD_ERROR
STANDARD_ERROR_LITE
STANDARD_ERROR_LOGIN

scroll down in each template and find that start of your phrases which looks like this:

<ol>
							<li>{vb:rawphrase not_logged_in_fill_in_form}</li>
							<li>{vb:rawphrase may_not_have_sufficient_privileges}</li>
							<li>{vb:rawphrase administrator_may_disabled_account}</li>
						</ol>

Change the HTML list tags to dd like so <li></li> -> <dd></dd>

remember to change each non child style you are also using aside from default
